AlphaSigOU is, as always, a fount of information.

Here's an amusing story for ya: I was on a plane once where we taxied away from the gate and were then held on the ground (apparently there was a ground stop at our destination and they didn't bother acting on it until AFTER we'd left the terminal ) - so the plane was parked out of the way somewhere. The captain announced that we'd be delayed about 2 hours. So everyone went for the "obscenely-expensive seatback air phones" to tell friends, family, and colleagues about the delay. About ten minutes later, AFTER everyone had paid $5/min or whatever it's up to now, the captain announced, "Oh, by the way, you can use your cell phones."
